【摘要】：齒輪傳動(dòng)是應(yīng)用最廣泛的機(jī)械傳動(dòng)技術(shù)，距今已有五百多年的歷史。根切現(xiàn)象限制了齒輪的傳動(dòng)空間。為了避免齒輪的根切，就必須犧牲齒輪的傳動(dòng)空間。空間曲線嚙合輪（Space Curve Meshing Wheel，SCMW）的產(chǎn)生，從根本上消除了齒輪的根切現(xiàn)象，推動(dòng)了齒輪傳動(dòng)技術(shù)的發(fā)展。 本文圍繞如何提升SCMW傳動(dòng)精度做了相關(guān)的研究。首先，在激光熔融快速成型制造技術(shù)的基礎(chǔ)之上，研究了SCMW鉤桿表面質(zhì)量改進(jìn)技術(shù)，，從而提高SCMW的傳動(dòng)精度。其次，在SCMW傳動(dòng)的過(guò)程中，由于裝配誤差和負(fù)載作用，其傳動(dòng)精度也會(huì)降低。本文研究了裝配誤差、負(fù)載以及重合度對(duì)傳動(dòng)精度的影響，并提出相應(yīng)的解決方案來(lái)提高傳動(dòng)精度。 具體來(lái)講，本文進(jìn)行了以下幾個(gè)方面的工作： 1.研究了電解擦削精加工技術(shù)，設(shè)計(jì)了SCMW的電解擦削的加工工具和加工設(shè)備，并設(shè)計(jì)相應(yīng)的加工方案對(duì)SCMW的嚙合鉤桿進(jìn)行精加工，通過(guò)提高其表面質(zhì)量來(lái)提高傳動(dòng)精度。 2.研究了裝配誤差對(duì)SCMW傳動(dòng)精度的影響。根據(jù)鉤桿中心線方程，結(jié)合空間幾何學(xué)知識(shí)，求出嚙合鉤桿的曲面方程。然后根據(jù)齒面接觸分析理論，結(jié)合空間曲線嚙合輪的裝配誤差模型，推導(dǎo)裝配誤差存在時(shí)的傳動(dòng)誤差。從而計(jì)算出存在裝配誤差的情況下，SCMW的傳動(dòng)誤差和重合度的變化。為控制和減少傳動(dòng)誤差提供理論依據(jù)，并在實(shí)際的應(yīng)用過(guò)程中，為控制傳動(dòng)誤差提供相應(yīng)的解決方案。 3.研究了負(fù)載對(duì)SCMW傳動(dòng)精度的影響。分析其傳動(dòng)過(guò)程中的鉤桿受力與變形情況，計(jì)算在嚙合過(guò)程中鉤桿的實(shí)際曲面方程。并根據(jù)齒面接觸方程，計(jì)算運(yùn)動(dòng)過(guò)程中接觸點(diǎn)的各個(gè)曲面參數(shù)與實(shí)際傳動(dòng)角度。運(yùn)用MATLAB擬合出其傳動(dòng)誤差曲線，從而計(jì)算傳動(dòng)負(fù)載對(duì)傳動(dòng)誤差和重合度的影響。為了提高傳動(dòng)精度，根據(jù)計(jì)算出的傳動(dòng)誤差曲線和各個(gè)接觸點(diǎn)的變形情況，提出一種鉤桿的修形方法對(duì)空間曲線嚙合輪的鉤桿修形。 4.研究了重合度對(duì)傳動(dòng)精度的影響。首先，根據(jù)重合度的定義，計(jì)算出重合度對(duì)空間曲線嚙合輪載荷分配的影響。其次，根據(jù)載荷分配規(guī)律，分析了重合度對(duì)鉤桿變形的影響，并根據(jù)鉤桿的變形情況，計(jì)算出實(shí)際的曲面方程，最后，計(jì)算運(yùn)動(dòng)過(guò)程中SCMW傳動(dòng)誤差的變化情況，繪制傳動(dòng)誤差曲線，分析重合度對(duì)傳動(dòng)精度的影響。從而為空間曲線嚙合輪的重合度的設(shè)計(jì)提供理論依據(jù)。 盡管本文圍繞提升空間曲線嚙合輪的傳動(dòng)精度做了以上研究，取得了一定的成果，但是仍然存在一些不足，如空間曲線嚙合輪的摩擦與潤(rùn)滑并沒(méi)有進(jìn)行研究。齒輪副的磨損將是影響傳動(dòng)精度的重要因素，這些工作尚需后續(xù)研究。
[Abstract]:Gear transmission is the most widely used mechanical transmission technology, which has a history of more than 500 years. The phenomenon of root cutting limits the transmission space of gear. In order to avoid the root cutting of gear. It is necessary to sacrifice the transmission space of the gear. Space Curve Meshing Wheeler WMWs of the space curve meshing wheel are produced. The root cutting phenomenon of gear is eliminated fundamentally, and the development of gear transmission technology is promoted. This paper focuses on how to improve the accuracy of SCMW transmission. Firstly, on the basis of laser melt rapid prototyping manufacturing technology, the surface quality improvement technology of SCMW hook rod is studied. In order to improve the transmission accuracy of SCMW. Secondly, in the process of SCMW transmission, because of the assembly error and load, the transmission accuracy will also be reduced. The assembly error is studied in this paper. The influence of load and coincidence degree on transmission accuracy is discussed, and the corresponding solutions are put forward to improve transmission accuracy. Specifically, this paper has carried out the following aspects of work: 1. The finishing technology of electrolysis polishing is studied, the machining tool and equipment of SCMW electrolytic polishing are designed, and the corresponding machining scheme is designed to finish the meshing hook rod of SCMW. The transmission accuracy is improved by improving the surface quality. 2. The influence of assembly error on the accuracy of SCMW transmission is studied. According to the centerline equation of hook rod and the knowledge of spatial geometry, the surface equation of meshing hook rod is obtained. Combined with the assembly error model of the space curve meshing wheel, the transmission error when the assembly error exists is deduced, and the case of the assembly error is calculated. The change of transmission error and coincidence degree of SCMW provides a theoretical basis for controlling and reducing transmission error and provides a corresponding solution for controlling transmission error in practical application. 3. The influence of load on the accuracy of SCMW transmission is studied. The force and deformation of the hook rod in the transmission process are analyzed, and the actual curved surface equation of the hook rod in the course of meshing is calculated, and the contact equation of tooth surface is calculated. The surface parameters of contact point and the actual transmission angle are calculated, and the transmission error curve is fitted by MATLAB. In order to improve the transmission accuracy, according to the calculated transmission error curve and the deformation of each contact point, the influence of transmission load on transmission error and coincidence degree is calculated. This paper presents a modification method of hook bar for space curve meshing wheel. 4. The influence of coincidence degree on transmission precision is studied. Firstly, according to the definition of coincidence degree, the influence of coincidence degree on load distribution of space curve meshing wheel is calculated. Secondly, according to the law of load distribution. The effect of coincidence degree on the deformation of hook rod is analyzed. According to the deformation of hook bar, the actual surface equation is calculated. Finally, the change of SCMW transmission error during the course of motion is calculated, and the transmission error curve is drawn. The influence of the coincidence degree on the transmission accuracy is analyzed, which provides a theoretical basis for the design of the coincidence degree of the space curve meshing wheel. Although this paper has done the above research around the transmission accuracy of the lifting space curve meshing wheel, and achieved certain results, but there are still some shortcomings. For example, the friction and lubrication of the space curve meshing wheel are not studied. The wear of the gear pair will be an important factor affecting the transmission accuracy, which needs further study.
